本論文主要目的是探討光學非球面鏡片在製作的過程中，包括成型與拋光階段的加工參數對鏡片的形狀精度與表面粗糙度之影響。藉由不同加工參數的實驗結果，提出改善鏡片形狀精度誤差與表面粗糙度要求所需較為有效的加工改進方法。
本文的實驗分為成型(Generation)、研磨(Lapping)與拋光(Polishing)三大部分去探討各階段不同的加工參數對鏡片精度影響的程度。成型部分，主要是探討砂輪傾角與工件轉速對鏡片形狀精度與表面粗糙度的影響。研磨(Lapping)部分，主要是探討壓力分佈均勻與否、磨砂粒徑大小、拋光墊種類對鏡片形狀精度與表面粗糙度的影響。拋光部分，主要是針對鏡片的表面粗糙度做改善。拋光後鏡片的形狀精度(P-V)可達0.6929μm，表面粗糙度(Ra)可達124 nm。

The purpose of this research is to study about the effect of various parameters on the aspheric lens during the generating and polishing process. By applying the experiment results, an effective method is proposed for improving the form accuracy and the surface roughness.
The experiment of this research is taken into three stages including the lens generation、lapping and polishing. We researched the effect level of the lens accuracy when applying the different working conditions to each stage. In the first stage of the experiment, we discussed the effect of the lens form accuracy and surface roughness by altering the angle of inclination between the cup wheel and the lens surface, and also the work rotational speed. In the second stage of the experiment, we discussed the effect of the lens form accuracy and surface roughness by applying the different abrasive size and lapping pads. In addition, we also concern the uniformity of the lapping pressure distribution. In the third stage of the experiment, our research is focused on the lens surface roughness. After polishing process, a form accuracy of 0.6929μm P-V and a surface roughness of 124 nm Ra were obtained.
